HP XC System Software Installation Guide Version 3.0

Appendix D (page 105) describes how to configure the line monitoring cards for each interconnect type.
Return to this chapter when you are finished configuring the cards.
Configure sendmail (Required)
LSF requires a mail program to send job output to users submitting jobs and to send administrative messages
to the LSF administrator.
By default, LSF uses the mail program /usr/lib/sendmail. The sendmail service is installed by default
on the head node in /usr/lib/sendmail, but you must configure it to meet your site requirements.
sendmail Configuration Requirements on an HP XC System
Although Linux sendmail typically functions correctly as shipped, current XC host naming conventions
cause sendmail to improperly identify itself to other mail servers. This improper identification can lead to
the mail being rejected by the remote server.
This problem is easily remedied by taking the following steps on all nodes with an external connection that
will be sending mail:
1. Be sure you know the fully qualified host name associated with the node's external IP address.
2. On the head node, add an entry for the IP address and fully qualified domain name to the top of the
/etc/hosts file. Make your entry above the comment #XC-CLUSTER Do Not Edit Below this
Line . Your entry should look similar to the following
192.0.2.3 southpole.com
In the previous example, southpole.com is the fully qualified domain name, and 192.0.2.3 is its
external IP address.
3. Save your change and exit the file.
4. Use the text editor of your choice to open and edit the following file:
/etc/mail/submit.cf
5. Locate the section of the file that looks like this:
# my official domain name
# ... define this only if sendmail cannot automatically determine your domain
#Dj$w.Foo.COM
6. Uncomment the macro and include your fully qualified host name. The entry should look similar to the
following:
Djfully.qualified.name.com
Using our example domain name, the line looks like this:
Djsouthpole.com
7. Save your change and exit the file.
8. Restart sendmail:
# service sendmail restart
Users may need to have .forward files in their home directories to specify where mail is to be sent in order
for the sendmail service to properly forward mail to users.
Consult any third-party Linux system administration reference manual if you need more information about
configuring sendmail.
To use a mail program other than sendmail, you must set the LSB_MAILPROG variable in the
/opt/hptc/lsf/top/conf/lsf.conf file to the appropriate mail program after the system configuration
is complete.
Create the /hptc_cluster File System (Optional)
During the software installation process, you had the option to create a disk partition for the /hptc_cluster
file system somewhere other than the installation disk on the head node.
Do one of the following now if you did not create the /hptc_cluster file system on the system disk on
the head node:
